Onyx Vibe pairs up our reliable Vibe symmetric core with a new CT Reactive Plus coverstock. The Onyx Vibe gives bowlers a ball motion that we haven’t had in our Hammer line for quite some time. Bowlers will see a very aggressive arc throughout the entire lane with the Onyx Vibe. This is by far the most aggressive Vibe made to date. It comes in a very sharp Onyx Sparkle color with Gold Flake engraving.
